Update to vcon-core-01 compliance

[howethomas]

Summary

• Updated library to be fully compliant with IETF draft-ietf-vcon-vcon-core-01
• Added comprehensive type definitions and validation
• Added 3 tutorial examples demonstrating real-world usage
• Expanded test coverage to 61 tests

Changes

Core Library

• types.ts: Full vcon-core-01 interfaces (DialogType, DialogDisposition, Encoding, SessionId, etc.)
• Dialog: New constants (DIALOG_TYPES, DISPOSITIONS, VALID_ENCODINGS), validation method
• Attachment: Params-based constructor, external/inline data methods, validation
• Party: Added sip, did, timezone fields; hasIdentifier(), getPrimaryIdentifier(), validate()
• Vcon: Extension support (addExtension, addCriticalExtension), groups, enhanced API

Documentation

• Complete API reference in README.md
• CLAUDE.md for AI assistant instructions
• 3 tutorial examples: text-chat, call-recording, video-conference

Breaking Changes

• Encoding type: only 'base64url', 'json', 'none' (removed 'base64')
• Attachment constructor: now takes params object
• Dialog types: 'recording', 'text', 'transfer', 'incomplete'

Test plan

• All 61 tests passing (npm test)
• Build succeeds (npm run build)
• All 3 examples run successfully (npm run examples)

Note

Implements full vcon-core-01 compliance across types and classes (new encodings, fields, validation, and APIs), adds examples and docs, and expands tests and scripts.

• Core API (vcon-core-01)
  • src/types.ts: Add comprehensive spec-aligned types (DialogType, DialogDisposition, Encoding, SessionId, Group, Redacted/Amended), VCON_VERSION, and richer Party/CivicAddress.
  • src/dialog.ts: New constants (DIALOG_TYPES, DISPOSITIONS, VALID_ENCODINGS), switch to mediatype, allow parties int or array, add addExternalData/addInlineData, helpers (isRecording/isText/...), and validate().
  • src/attachment.ts: Params-based constructor, support inline/external data with helpers, VALID_ENCODINGS, toDict() date ISO, and validate().
  • src/party.ts: Add sip, did, timezone, helpers (hasIdentifier, getPrimaryIdentifier), validate(), and PartyHistory improvements.
  • src/vcon.ts: RFC3339 timestamps as strings, extension framework (addExtension, addCriticalExtension, hasExtension), addGroup, updated addAttachment/addAnalysis, getters/setters for subject/meta/redacted/amended, export vcon default to VCON_VERSION.
  • src/index.ts: Export new types/constants.
• Breaking changes
  • Encodings restricted to base64url, json, none (remove base64).
  • Attachment now takes a params object.
  • Dialog types constrained to recording, text, transfer, incomplete; prefer mediatype over mimetype.
• Docs & Examples
  • README.md: Overhauled with API reference, compliance notes, and usage.
  • examples/01-text-chat.ts, 02-call-recording.ts, 03-video-conference.ts with new npm scripts in package.json.
  • CLAUDE.md: Project overview and guidance.
• Tests
  • Update/add tests for dialogs, attachments, parties, vcon (validation, constants, new APIs); broaden synthetic vCon coverage.
